Complex Bearings
NTN complex bearing is composed of a radial needle for the same purpose, this complex bearing saves the
roller bearing to support radial load and a thrust ball required installation space and thereby can contribute to
bearing or a thrust roller bearing to support axial load making the overall construction of an equipment more
which are integrated into one bearing unit. Comparing compact.
with individual use of a radial bearing and a thrust bearing
